Bad Service

I was at Vodacom the 2 Jan 2019. The service was fine. The woman who helped us(who's name I did not get) said that the deal I wanted was not accepted by Vodacom and they need to approve it and it will take 24 hours. All good and well, I can understand that. I got an sms on the 3 Jan 2019 stating that it has bewn approved. I went to the Vodacom Shop and I waited for 30 min. I then asked someone if they can help us and told me the person who helped me the previous time must... so they went to call her. She saw us, did not come to communicate and the other person that called her said she was busy and she will help us when she is done. After another 10 min we asked again where she is and they said she opened the safe 5 min ago and it will take another 10 min. It is dissapointing that no one can communicate with us nor help us. I feel like leaving everything and going to anotherc service
